OpusFSI Beta Versions 4.65.6 Available

First OpusFSI Beta for the new Prepar3D v3.2 release (see SimForums).

Enhanced Live Weather Assistant (LWA) Map Auto Zoom feature effective at both your departure and destination points. The Live Weather Engines (LWE) Maximum Wing Flex level (0 to 4) can now be adjusted in the Weather Preferences dialog.

Station data rebuilt using the 'Rebuild Station Data' option in the Configure dialog is now loaded and/or appended to the standard OpusFSI station data both after completing a rebuild operation and on start up. This change not only allows addon stations to be loaded but also allows arguments and restrictions to be used with Pete Dowson's MakeRwys.exe utility program.

OpusFSI Release Versions 4.64.0 Available

Licensed OpusFSI Upgrade users no longer need to have a valid OpusFSX licence file installed. As a result, no further OpusFSX to OpusFSI Upgrade purchases are possible (only re-installs). We have also changed the procedures used to modify all aircraft.cfg SimObject files. The cfg files are now modified to store data in the following order,

<general configuration settings> <OpusFSI camera definitions> <standard camera definitions>

In other words, the cfg file content is modified to insert (rather than append) all Opus camera definitions in between the aircraft's general configuration settings and all standard aircraft camera definitions. The software will also create a backup (.bak) copy of the aircraft.cfg files the first time it is used.

This release is fully compatibility with Lockheed Martin's Prepar3D Versions 2 and 3 for both server and client programs.

Corrected a problem saving historic World Weather Themes for all simulator types, and handling Windowed Views with Lockheed Martin's Prepar3D Version 3 for both server and client programs. These betas contain the latest updates and corrections for full compatibility with Prepar3D Version 3.

Price reduced to $44.95

Includes the Live Weather Overview / Locator feature for the FSISERVER (see document and topic on SimForums).

Added a World View camera type and appropriate means of creating, cloning and editing World View cameras on both the main server and client systems. See Live Camera Guide or details posted in the 'OpusFSI World Views Beta' SimForums topic.

Improved the turbulence calculations and DHM control when the Live Weather Engine is not active. These effects are limited to lower atmospheric and 'in cloud' effects. Inversion layer effects, site specific effects, and upper atmospheric effects such as CAT (Clear Air Turbulence) cannot be determined when the LWE is inactive as all detailed OpusFSI weather map and GRIB forecast data is missing. Corrected a problem handling and displaying multiple Windowed views on Live View client systems. Improved Dynamic Wind Control (DWC).

The LWA Maps now include options to both examine and plot the SID and STAR fixes and routes for any aerodrome in the world.

Added an Export World Weather option to the Weather dialog. When enabled the world wide GRIB and METAR data will be saved in the \OpusFSI\Weather folder. This data is intended for use by third-party flight planning packages. 

Added an Enable GRIB Download in Flight option to the Weather Downloads dialog. When enabled the world wide GRIB data will be downloaded during a weather update, either on the ground or in flight, whenever it is found to be either incomplete or invalid (e.g. is older than the specified GRIB Validity Period). When disabled, GRIB download and decoding will only take place when the aircraft is on the ground (e.g. either before flight or after landing).

The GRIB Validity Period in the Weather Downloads dialog can now range from 3 to 240 hours in increments of 3 hours, matching the GRIB forecast data temporal resolution. The GRIB cycle data hour offset is now displayed in the Spy window text, in the on-screen Upper Atmosphere report, and in the OpusWeatherReport (GRIB) text report file.

OpusFSI Release Version 4.48.7 Available

New small footprint size adjustable LWA Map options added replacing older small footprint Wx Maps. The new maps allow geographic data to be displayed in a similar fashion to the main LWA Map. Up to four small footprint LWA Maps can be displayed on either the server or a networked client system.

A Rebuild Station Data option has been added to the FSISERVER Configure dialog. This option can be used to build system specific station (aerodrome) data, including all addon airports and airfields you may have installed. This data contains details of all simulator stations (aerodromes) along with all runway and communication frequencies.

Weather Relocation options within the Weather dialog will relocate the weather using the user specified FROM and TO locations. The ICAO code for either the current point of departure or the specified destination would typically be specified in the TO box. To aid entry, an empty TO box will automatically be filled in with the nearest aerodrome details whenever the FROM box is edited.

Corrected a problem with the turbulence and wind shear data injection within wind layers. The LWE now injects the rounded up average of all OpusFSI turbulence levels covered by the altitude range of the wind layer.

OpusFSI Release Version 4.47.3 Onwards..

Added configuration options for Microsoft FSX Steam Edition. 

World Weather Themes allow you to save both the world's current METAR reports along with all the current worldwide GRIB forecast data into a named OpusFSI World Weather Theme. These themes can be loaded at any future time to recreate the global weather, including all lower and upper atmospheric data. The user can then fly in the saved theme weather as if the data was current. Ideal for continuing a saved flight or recreating a saved weather scenario.

Includes the OpusPDK Interface for fast and efficient camera control on Prepar3D v2.4 systems. Upgraded turbulence and wind shear data injected into the simulator for coordinated turbulent motions of the aircraft. Delay command line argument added to assist auto startup. Improved GRIB data download procedures to auto select the best available NOAA server on download. GRIB decoding improved to take acccount of incomplete GRIB cycle data posted by NOAA.

Improved Cloud Smoothing, Dynamic Wind Control, and Prepar3D Volumetric Fog effects including Low Overcast and Reduced Upper Level Visibility options.

Makes use of the new NOAA GRIB Query Server (replaces the old query server). This server is used to minimise GRIB forecast data download times. The new GRIB Query data file is typically 4.1Mb in size compared with the FULL GRIB data file size of 19.3Mb. A Save World Weather Theme option has also been added to the Live Weather Addon menu.

We have added a Show Traffic option to the server and client LWA Maps indicating the aircraft within a configurable 20 to 120 mile radius of your current position. 

The screenshot shows Live Traffic at EGBB Birmingham, several aircraft are parked at the gates, one aircraft is at the hold for 33, and one aircraft on final approach (shown in red because I was sat on the ground, hence the traffic is within 2000 feet of my altitude).

The LWA Maps on the client and server systems, and the on-screen Destination and Alternate Weather Reports now list all available runways in preferred order of use (reading left to right) based on the current surface wind at the site. The LWA Maps also show all relevant Nav and Com frequency data for any identified aerodrome or met station. A left-click 'Lock' mode has been added to the LWA Map to lock the displayed data to a particular station. By right-clicking on stations of interest any number of LWA Weather Monitor boxes can be displayed, each showing all relevant data on the station, all available runways (in preferred order of use), all Nav and Com frequencies, and the current weather information. By right-clicking on any traffic symbols any number of LWA Traffic Monitor boxes can be displayed, each showing all known information about the traffic, including distance and bearings to its destination and your user aircraft. Traffic is coloured, GREY indicates traffic on the ground, GREEN indicates airborne traffic that is > 2000ft above or below your current altitude, and RED indicates airborne traffic that is <= 2000ft above or below your current altitude.

An Auto Zoom option has also been added to the LWA Maps to automatically zoom the map in as you approach your destination aerodrome. The map will zoom in sufficiently to show all taxiways as an aid to taxiing to the gates or parking area.

An additional Low Level GRIB Forecasted Winds and Temperature data option as been introduced for accurate winds and temperatures throughout the lower atmosphere. This data is also used to determine additional zones of turbulent air and inversion layers from the ground up to supplement the current intelligent turbulence control.

New improved Prepar3D Volumetric Fog effects are produced by intelligent visibility layering which also takes into account any low level inversion layer.

Multi-Layered Clouds are now enhanced within the Live Weather Engine. The LWE references additional cloud, surface, and atmospheric data to determine its low level (up to 6000 feet AGL) and Mid level (6000 to 26000 feet AGL) cloud coverage which is blended with the 'actual' METAR data. The high level cloud data is also used to control (enable or disable) localised cirrus cloud.

Panning Sequences such as aircraft 'walk arounds' and 'fly arounds' may now be imported or created. A set of pre-configured examples are provided for you to try. The LCC can be used to define each eyepoint in the sequence and tools are provided to copy, flip and duplicate sections of the sequence which makes the creation of panning sequences quick and easy. 

OpusFSI Panning Sequence Editing

OpusFSI is fully compatible with the latest release of P3D version 2.4. Click on the image below to view a video.

OpusFSI is a paid upgrade to OpusFSX and includes the following new features and enhancements,

OpusFSI Live Weather Assistant Map

OpusFSI Live Camera editing

OpusFSI Live Camera management

OpusFSI is fully compatible with the latest release of P3D version 2.3. Click on the image below to view a video.

OpusFSX Release Version 3.50.2 Available

Improved Dynamic Wind Control for rapidly changing calm winds. Changes to the ButtKicker audio control data in an attempt to improve the stability of the Microsoft 'wdmaud' driver. Enhanced METAR decoding for Canadian reported minimum visibilities.

This release includes improved camera transition options allowing greater flexibility and better aircraft walk and fly arounds to be created. The transition speeds can now be slowed down to near walking pace with a slight acceleration and deceleration at the start and end of the camera movement.

This release also includes a reorganised Camera Control dialog which adopts a more intuitive left to right and top down order for the camera configuration options. Camera editing no longer recognises aircraft and rotorcraft that do not have panel folders. The injected wing flex data has been increased up to the maximum allowed level within the simulator. High level cloud cover defined in the RMK section of the METAR is also decoded by the LWE.

The visibility has been adjusted to generate more realistic poor visibility at lower levels especially when there is a reduced surface visibility resulting from fog, mist, or haze. We have also added a non-linear element to camera view transitions and modified the way zoom level changes are handled. The weather map data has been reordered and relabelled ready for future upgrades.

Spoiler (speed brake) deployment, landing and initial roll out vibration effects have been added to the ButtKicker audio control. The NOAA (Feb 2014) Met Station list has been updated.

The new improved and coordinated Dynamic Wind Targeting and Control measures are capable of completely eliminating wind shifts whilst still allowing accurate, dynamic, and varied real-world weather to be used within the simulator. These new measures allow both wind and temperature targets to be maintained accurately during all phases of the flight.

The improved Dynamic Wind Control is now constantly active whilst you are above 100 feet AGL and always attempts to smoothly adjust the ambient wind speed and direction toward the required target values.

New 'Actual' indication added to the Destination Weather Report to indicate when the weather inside the simulator matches the reported weather at the destination.

A Reverse Axis option has been added to the LCC Shortcuts Left/Right, Up/Down, Forward/Backward, Pitch Up/Down, Bank Left/Right, and Yaw Left/Right controller axes.

GPS Output feature for 3rd party Navigation and Flight Planning packages such as the excellent real-world SkyDemon PC software.

GPS Output feature for 3rd party Navigation and Flight Planning packages such as the excellent real-world SkyDemon PC software

Greatly improved coordination of all weather layering (i.e. winds, temperatures, visibilities, and cloud) within the Live Weather Engine including cloud smoothing layers. Improved Bump Aircraft turbulence and ButtKicker audio output control.

Extended Cloud Smoothing software introduced which helps minimise cloud popping during weather updates at all altitudes.

Eliminated view flickering in changing VC and 2D views especially noticeable in Prepar3D.

New Anti Wind Shift measures introduced which helps FSX cope with the wind gradients and prevent wind shifts during the climb up to FL200 and on up to your specified Max Cruise Altitude.

Volumetric Fog option introduced for P3D v2.

Bump Aircraft Turbulence improved with new 1,2 or 3 DOF options.

The ButtKicker Gamer2 package features a chair-mounted (single post type) tactile transducer that lets you really “live the game” Installing a dedicated audio device such as the Sound Blaster X-Fi Go PRO USB stick means that all low frequency BK audio control signals are completely separated from the normal simulator sound and will hence have no effect on your current sound system or current audio output

The ButtKicker Gamer 2 device control enables up to three ButtKicker devices to be assigned to an audio output and associated with a DHM X, Y, or Z accelerometer data axis. The ButtKicker options include taxiing, engine vibration, turbulent bumps, flaps, spoiler, landing roll out, and landing gear effects. Installing a dedicated audio device such as the Sound Blaster X-Fi Go PRO USB sound stick means that all low frequency BK audio control signals are completely separated from the normal simulator sound and will hence have no effect on your current sound system or current audio output. Please refer to the OpusFSX_ButtKicker.pdf.

Joysticks or controllers with POV (Point Of View or 8-Position Hat switches) can be used for LCC axes functions. Up to four POV or Hat switches can be supported for each controller device.

More Australian Site Effects have been included bringing the total number of site effects to 67. Site effects apply to the point of departure and destination ICAO.

Automatic cirrus generation is now based on the aircraft's current latitude.

The Site Effects feature introduces additional turbulence and wind shear within 80 km of your destination airfield resulting from local features such as terrain or even obstacles and buildings on approach. British sites with some well known International airports are included as standard. You can also configure your own customised site effects.

Live Camera Control (LCC) enables you to make adjustments to the current eye point for any VC, 2D, or Custom view using either,

This is useful for making seat adjustments, roaming about the cockpit, or flying or walking around the aircraft. The Set Camera feature within Live Camera Control sets temporary adjustments to views. This is useful to overcome the FSX bug which shifts the camera view slightly at different locations in the world.

The PMDG 777 upper wind and temperature wx file will now be created automatically when you activate your flight plan. Select WIND DATA REQUEST on the WIND page in the 777 and it will automatically load these values into the FMC. The LWE now accommodates systems running at increased simulation rates (requires the free version of FSUIPC4).

Further anti wind shift measures have been included within the Sim Friendly GRIB Data processing.

OpusFSX may reduce the surface visibility for CAVOK conditions to 10km or 16km depending on the average visibility in the area.

The OpusFSX client is now compatible with 3rd party packages such as WideView and WideTraffic.

General DHM Options have been added to the FSXSERVER's Configuration dialog. These options allow general DHM and associated 'Bump Aircraft' turbulence to be enabled for VC view modes, 2D view modes, and other general view modes without needing the Live Camera interface to set up camera views.

The Live Weather Assistant provides useful weather information for the current Opus 800 x 800 mile weather map displayed graphically as a mosaic of 6400 weather cells in either a large or small footprint map with options for Surface QNH, Surface Winds, Surface Visibility, Surface Temperature, Precipitation Levels, Low Cloud Cover, Cruise Level Wind, Cruise Level Temperature and Met Station Cover. The large map and up to six small Weather Maps can be opened and positioned on the screen.

Flight planning assistance includes Add-on Menu Report options to show the OpusWeather (METARs and optional TAFs), OpusWeatherReport (GRIB Data), OpusFlightReport (Flight Plan), and OpusSidStarReport (SIDs and STARs) text file reports within Notepad. iFLY type formated SID and STAR files are now recognised and decoded. 

You can import any Microsoft PLN formatted flight plan and all flight plans activated within the simulator are decoded and processed automatically.

GRIB data handling and upper wind and temp target injection has changed to improve the resolution of all upper wind and temperature targets throughout the weather map and hence throughout the injected weather region. The download and preparation of the GRIB forecast data can now be followed in the Opus Lower and Upper Atmosphere Report windows.

Client Side LWE Control has been added to enable you to control the weather and flight planning from a networked PC and display the various Opus Weather Report windows. 

A Live View Scan Rate (0 to 60ms) adjustment has been added to the FSXSERVER configuration to control the position update rate communicated to the server allowing you to match the preferred rate found using the Live View Server Test.

We have also combined our heuristic weather interpolation with perfect geodesic mapping within the simulator that results in accurate destination weather from over 200km away.

Live Weather Reports now provide a perfect long range (400 mile) ATIS for your Local, Destination and up to 4 Alternate airfields or sites. 

The OpusFSX Lower and Upper Atmosphere reports also provide detailed winds and temperatures aloft targets derived from the GRIB forecast data.

The second phase of flight planning assistance has been included which extracts your navigation points, providing detailed Flight Plan En Route Weather Reports. 

Camera Import and Export options are included. User Camera Definition Files (CDFs) are available on our Downloads page for import.

Brief Description

OpusFSI The ultimate Flight Simulator Interface for FSX and Prepar3D with,

Live Weather Engine for real world live weather updates,
Live Camera for view control and dynamic head movements, and
Live View for synchronized multi-screen networked displays.

OpusFSI helps take reality to the next level by combining three excellent programs into one user friendly interface, setting new standards of performance and realism throughout its novel design. The OpusFSI interface is ideally suited to both standalone and networked FSX/P3D systems making it the ideal addon for cockpit builders and general users alike.

On standalone systems, OpusFSI incorporates two superb functions through its Live Weather Engine and Live Camera options.

The Live Weather Engine uses our unique methods of weather update to provide the most advanced software in the marketplace and set new standards for weather updating for the FSX and Prepar3D flight simulators. These methods provide the most detailed, realistic and efficient weather updating service and offer huge benefits over the sluggish, inaccurate and totally unrealistic update methods employed by others. You can also load historic weather from within the last 24 hours. OpusFSI allows you to create and name your own themes based on the current live METAR reports or import your own custom METARs.

The screenshot below illustrates the detailed weather generated by our Live Weather Engine,  illustrating foggy weather in P3D.

Live Camera provides excellent camera creation, control and docking facilities through its user friendly interface, totally eliminating the need to alter any of the simulator's controls. You can create many useful views that are not included as standard in your sim and also control the transition speed between these different views. This can be coupled with Live Camera Control and a dedicated 6-axis GamePad controller to wander or float around the cockpit or exterior to your heart's content.The Live Camera interface also includes support for Windowed Views and provides an ultra-realistic Dynamic Head Movement option (virtual cockpit camera shake) utilising actual 'real-life' capture 3D accelerometer data and Automatic Head Movements to assist the pilot whilst taxiing and banking in a turn.

Multiple windowed views on the OpusFSX Server

On networked systems, irrespective of the size and complexity of your system, whether your system consists of a main 'flying' PC with a single networked laptop client, or a more elaborate multi-computer networked system; the Live View interface, with its ultra high-performance IPC communications, unique Client Side Smoothing software, and perfect synchronization of aircraft status, weather and cloud formations, will provide you with the highest possible networking performance. Whether you simply want an additional controllable display to provide further scenic or external view options, or wish to create a multi-screened panorama for your FSX or Prepar3D experience, Live View offers you the ideal hassle free user-friendly solution.

Your main 'flying' Opus server is the machine through which you control the aircraft. The networked client Opus systems are synchronised to the server through multiple ultra high-performance IPC links, the client systems are used primarily as view controllers. The networked systems allow you to create a multi-screened simulator system without placing the full workload and burden on your main system.

From this set up it therefore follows that all in-cockpit or instrument panel views used to control the aircraft must be displayed on the main server. All other views (scenic or external) can be offloaded onto the client systems. You can create wide panoramic vistas this way, or additional external aircraft views, without draining the resources on your main system or degrading its performance.

Client Side LWE Control enables you to control the weather and flight planning from a networked PC and display various Opus Weather Reports. Live Weather Assistant maps can also be displayed on a client PC.

Future Development Plans

Live Traffic Synchronization

Live Traffic will supplement the Live View multi-screen networked displays by synchronizing all AI traffic across the Opus network.

Device Drivers

The device drivers provide an interface to the popular panels and addon hardware for FSX. Each device driver will interface to the relevant aircraft simulation thereby eliminating the need to install separate drivers dedicated to each aircraft.

CPFlight's MCP737PRO panel

All device drivers are aware of any new aircraft selections even if the aircraft is changed in mid-flight. The appropriate interface (SimConnect, FSUIPC4 or the manufacturer's SDK) will be initialised and employed automatically whenever necessary.
